The proposal would comprise 119 wind turbines, with a maximum height of 150 metres, and associated powerlines and access roads. Two Endangered Ecological Communities (EECs) were identified within the study area, namely, Ribbon Gum – Mountain Gum Woodland (EEC – Ribbon Gum – Mountain Gum – Snow Gum Grassy Forest/Woodland of the New England Tableland Region) and Yellow Box Woodland (EEC White Box Yellow Box Blakely's Red Gum Woodland). No threatened flora species as listed on the Threatened Species Conservation Act 1995 (TSC Act) and Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act) were identified within the study area during field surveys. Potential habitat within the study area was identified for three threatened flora species identified during database searches. Assessment of the potential level of impact on EECs and threatened flora species listed under the TSC Act identified one EEC and four threatened flora as potentially impacted by the proposal. For EECs and flora species the positioning of wind turbines in areas to avoid forest/woodland vegetation resulted in proposed powerline easements and access roads as requiring most woodland/forest vegetation removal. The relatively small area of vegetation that would be removed for the wind farm in relation to much larger amount available in the immediate area resulted in a finding of no significant impact on EECs or threatened flora species listed under the TSC Act. Three threatened fauna species were recorded during field surveys namely, the Eastern Bentwing- bat (Miniopterus schreibersii), Little Pied Bat (Chalinolobus picatus) and Varied Sittella (Daphoenositta chrysoptera). Potential habitat within the study area was identified for five threatened species during database searches. Assessment of the potential level of impact on threatened fauna species under the TSC Act identified seven threatened fauna species as potentially impacted by the proposal. The seven fauna species are the Turquoise Parrot (Neophema pulchella), Grey-headed Flying-fox (Pteropus poliocephalus), Eastern Bentwing-bat, Yellow-bellied Sheathtail-bat (Saccolaimus flaviventris), Greater Broad-nosed Bat (Scoteanax rueppellii), Greater Long-eared Bat (Nyctophilus timoriensis) and Little Pied Bat. The proposal was considered unlikely to have a significant impact on any of the seven threatened fauna species listed under the TSC Act. The proposal was also found to have no significant impact on any ecological communities, threatened species or migratory species as listed under the EPBC Act. Recommendations have been made to minimise and monitor the potential impacts of the proposal, including the implementation of a Construction Management Plan, an Environmental Management Plan and an Adaptive Management Plan. Offsets will also be provided to compensate for the loss of impact vegetation and habitat.

This study by RPS was undertaken as part of the Environmental Assessment (EA) to support an application for Project Approval under Part 3A of the EP&A Act. The report has been structured and conducted to fulfil the requirements of the Environmental Planning and Assessment Act 1979 (EPA Act), the TSC Act and the Fisheries Management Act 1994 (FM Act). Assessment of the proposal under the requirements of State Environmental Planning Policy No. 44 (SEPP 44) – ‘Koala Habitat Protection’ is included. Consideration of the proposal has also been undertaken in relation to the Commonwealth EPBC Act. Director General’s Requirements (DGRs) have been issued by the NSW Department of Planning (DoP) for the project. The DGRs identify certain requirements that must be incorporated into the flora and fauna assessment aspect of the project.
